Php 数据存储优化

我有一个表格，表格中的新行可以通过点击添加/删除按钮动态添加/删除

当我试图将新添加/删除的行保存回数据库时，问题就开始了。我设法使用jQuery的Ajax来保存数据，所以我没有使用post-var，而是“收集”每个输入上的所有数据。我设法获取所有这些数据并将它们发送到存储它们的store.php

我的问题是，如何用很少的查询保存我的更改，我的意思是，这是store.php发送到我的mysql服务器的输出：

UPDATE transport SET transporttype = "2" WHERE id = 6
UPDATE transport SET transporttype = "1" WHERE id = 7

无需告诉您，这非常慢，大约需要5秒来逐个存储所有数据。

您可以利用：

它所做工作的小结：

如果指定“在重复密钥更新时”，并插入一行，则 将导致唯一索引或主键中出现重复值 执行旧行的更新

如果您是从PHP脚本运行这些查询，那么应该确保您使用的是准备好的语句（mysqli或PDO）。如果您使用的是常规的mysql扩展，那么每次查询都会往返到数据库服务器。但是，使用准备好的语句，您可以将类似的查询分组到一个准备好的语句中，并使用不同的数据执行多次。

您的意思是我可以准备一次查询，然后每次使用不同的变量执行？它真的更快吗？如果准备SQL语句，数据库服务器将缓存查询，允许您使用不同的数据多次执行查询。例如，您将为前6个查询创建一个准备好的语句，并执行6次。然后，您将为后面的6个查询创建另一个prepared语句，依此类推。仍然存在一个问题，当表名永远不相同时，我不能使用prepared语句，有什么提示吗？将相同的查询分组到prepared语句中。示例：transporttype将有它自己准备好的语句，并且您将使用不同的数据执行该语句三次：更新传输集transporttype=：transporttype，其中id=：id

INSERT INTO table (id,Col1,Col2) VALUES (1,1,1),(2,2,3),(3,9,3),(4,10,12)
ON DUPLICATE KEY UPDATE Col1=VALUES(Col1),Col2=VALUES(Col2);
